WREETCH.

To all whom it may concern:

Be it known that we; Prm'nn JOSEPH CnoLLA and PETER JOSEPH. SoHMITz, subjects of the Queen of the Netherlands, and residents of Volkenburg, Netherlands, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to a wrench, with improved means for allowing a ratchetlike use of the same, the tapered ends of a handle for the wrench, manner around a nut.

The accompanying drawing shows improved arrangement.

Figure 1 is a plan View of the same in its use for tightening the nut, and Fig, 2 a similar view, showing the action of the wrench when turned in opposite direction.

The ends of a metal rod a, which serves as handle for the wrench are fiat and so wrought that they become thinner and thinner toward their sharp-ended extremity, the same being then placed in spiral windings 6 around a nut 0. Upon turning the wrench in the direction for. tightening the nut, the

rod, which serves as are wound in spiral the this being obtained in that Specification of Letters Yatent.

spiral windings are iirtniy gripped upon the nut. In the opposite direction, however, they yie d in springy manner, as this is shown in i ig. 2., wherehj, a ratchet-like use oi" the wrench is possible.

Of eonrse the same arrangement may he provided at the other end of the rod a, preferably for a different size of nut.

The manufacture of such wrenches is very simple and cheap. I

TWe elaim:

A 'vvreneh. comprising in combination a handie with flat and gradually tapered ends designed to be wound in spiral manner QIOt'intli nuts and adapted to be firmly attracted upon the same when tightening the nut out to yieid in springy mannerwhen turned in opposite direction, for the purpose set forth.
